From 433149130c31de3f63b17b4ce08b45dab208f7e8 Mon Sep 17 00:00:00 2001 From: Mikita Lipski Date: Tue, 17 Jul 2018 10:52:19 -0400 Subject: drm/amd/display: Pass connector id when executing VBIOS CT [why] Older ASICs require both phys_id and connector_id to execute bios command table. If we are not passing the right connector_id - it can lead to a black screen.
